Application of Reinforced Notebook in Maintenance System of Underground Pipeline

First, system overview

With the development of urban construction, traditional methods of overhauling underground pipelines are difficult to adapt. The management of water resources, drainage, natural gas, and power lines all require the use of more advanced devices. In addition to the use of traditional services, it also needs to incorporate the application of geographic information systems. The maintenance of the drainage system involves a series of complex tasks that require highly qualified staff and sophisticated technology. If these conditions are not available, leakage of drainage pipes may lead to contamination of groundwater and soil, thereby damaging the human body and the natural environment. On the other hand, if a defective pipeline is used to transport groundwater, the source of pollution is more likely to infiltrate the water system. Therefore, the wastewater must first be treated in a wastewater treatment plant.

In order to maintain normal operation, it is necessary to continue to clean and maintain the drainage system and regularly supervise the conditions of the pipelines, thereby discovering and solving problems such as pipe damage, groundwater intrusion, waste water discharge, plant roots, and debris intrusion. Today, the management, maintenance and quality control of a complex infrastructure such as a large urban drainage network system cannot be achieved without relying on technological equipment.

In addition to the high quality of the cleaning and discharge operations of the water resources system, more and more attention is paid to high efficiency, and a robust and portable computer can precisely meet this demand.

Second, the system requirements, br>

1. There are many pipeline entrances, which require the equipment to be easily carried;

2. It is possible to fall accidentally during operation and the equipment needs to resist falling and falling;

3, the outdoor operating environment is changeable, need to resist the invasion of rain, sand and dust;

4, keyboard night vision support underground operation.

5, long life

Third, the system description

The modern underground pipeline inspection system is composed of reinforced notebooks and inspection robots connected by cables. The whole set of equipment can move along with the inspection vehicles at each entrance. The signals and images collected by the maintenance equipment are transmitted to the ruggedized notebooks for real-time analysis and processing. At the same time, the ruggedized notebooks can be connected to the service terminals through wifi or 3G, and the conditions of the underground pipelines are transmitted back to the terminals for processing and preservation. Reinforced notebooks are used as data processing and display terminals to display and process underground pipeline data in real time, and the analysis data can also be printed out through a connected printer.
